发明名称 Device and method for protecting baled hay from moisture
摘要 A device for protecting baled hay from moisture damage includes a cover that fits over the hay bale and fasteners that project into the bale and connect with the cover so as to secure the cover in place. Each fastener has projections which lie in a single plane and when the fastener is turned so that plane is crosswise to parallel stalks of hay in the bale, the fastener remains firmly in place and cannot be easily withdrawn. On the other hand, when the plane of the projections is parallel to the stalks of hay, the fastener is quite easily emplaced or removed.
